energy recoveryA form of resource recovery in which the organic fraction of waste is converted to some form of usable energy. Recovery may be achieved through the combustion of processed or raw refuse to produce steam through the pyrolysis of refuse to produce oil or gas; and through the anaerobic digestion of organic wastes to produce methane gas
oil recovery vessel Boats used for recovering oil spilled at sea from oil tankers. The recommended procedure is to contain and physically recover the spill with or without the use of adsorbents. This approach entails three processes: 1. confinement of the spill by spill booms; 2. recovery of the spill by sorbing agents; 3. physical removal of the contained oil by oil pick-up devices
solvent recoverySolvent recovery is a widely practised form of recycling where spent solvents are distilled and reused. However, the cheaper solvents are often incinerated or dumped in hazardous waste landfill sites
